FRUIT AND VEGETABLE PEELING MACHINE.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed December 1, 1905. Serial No. 289,725.

which the vegetable or fruit is secured to a fork-shaft and rotatedthereby, said forkshaft being parallel with. the peeling-knife,

which is fed by a worm-spindle.

The object of my invention is to provide for a peeling-machine whichwill be simple in its construction and permit a rapid peeling ofvegetable or fruit.

With this and other objects in view my invention consists in thearrangement, construction, and combination of parts, and particularly inthe construction of thepeelingknife.

In order to make my invention more clear, I have illustrated the same inthe accompanying drawings, in which similar referenceletters denotecorresponding parts, and in which- Figure 1 is a front elevation of mypeelingmachine; Fig. 2, a plan view, and Fig. 3 a side view, thereof;Fig. 4, an enlarged vertical section through the knife-holderattachment; Fig. 5, a longitudinal section through the knife-holder;'1ig. 6, an enlarged side view of the knife; Fig. 7, a front view, andFig. 8 a cross-section; Fig. 9, a plan view of a detail part thereof,and Fig. an elevational view of the same.

In the drawing, 1 denotes a frame, the lower part of which is formed toa clamp 2, having a screw 3, by means of which. the frame can beattached to the edge of a table or stand. Rotatably borne in the frame 1is a wormspindle 4, which projects laterally therefrom and which isadapted to be driven by intermeshing gear-wheels 5 6, Figs. 1, 3, thewheel 6 being rigidly mounted on one of the extremities of the spindle,and the wheel 5 is borne in a bracket projecting rearward from theframe 1. The fork-shaft 7 is rotatively borne within the frame 1 andcarries at its rear end a gear-wheel 8, which is in meshing connectionwith the gear 5. The

gear-wheels may be revolved by hand by means of a handle 9.

Loosely mounted upon the worm-spindle is a head-piece or carriage 10,which is adapted to carry the knife 11 and which has adownwardly-projecting lug 12. This lug is adapted to engage a guide-rod13, rigidly fixed to the frame 1 and extending laterally parallel to theworm-spindle 4. The headpiece has a transversal bore 14 for the passageof the spindle 4, and at one of its sides it is reduced in its diameterand cylindrically turned to form a tubular projection or lug 15, onwhich the knife-holder 16 is mounted.

The knife-holder consists of an open cylindrical casing 17, from theouter circumference of which projects an arm. 18. This casing has in itsbase a cylindrical bore 19 to allow of the casing being slipped over thetubular lug of the carriage 10 and of loosely bearing thereon. Withinthis casing a coilspring 20 is arranged, one end of which is adapted tobe fixed to the inner wall of the casing, and the other end is bent to ahook 21. The width of the coil-spring 20 is somewhat larger than that ofthe inner circumferential wall of the casing 17 so that the said springwill somewhat project outward f1 om within the casing and engage in asecond casing 22,

that is similarly sha ed and adapted to be also loosely mounted on thetubular extension 15 of the head-piece at the side of the easing 17.From the inner wall of said second casing projects a pin 23, which whenturning the second casing 22 around will engage the hook 21 of the coil20 and wind up the latter. By means of set-screws 24 the secondcasing 22can be rigidly fixed to the tubular extension 15, so that the wound-upspring will tend to press down the arm 18, projecting from the casing 17The arm 18 extends toward the fork-shaft 7 and carries at its forwardend the knife.

The knife consists of a truncated hollow cone 25, which is open at oneend and at its other end has a perforated or cut-out wall.

The edge 26 at the open end of the cone is sharpened to form a blade. Aconicallyshaped piece 29 is adapted to loosely fit in the hollow coneand to project somewhat outward through the open end thereof. Extendingcentrally from the inner end of said conical piece 29 is a threadedprojection or pin 30, which is adapted to project through a thevegetable or fruit to be peeled.

bore 27 in the perforated wall of the cone 25 and to screw in a threadedbore 31, arranged in the holder 16. This piece 29 serves as a guide forthe conical knife 25, and the width of the annular space formed betweenthe outer circumference of the piece 29 and the inner circumference ofthe cone 25 will determine the thickness of the peel to be cut off.

As stated in the beginning, the head-piece 10 is loosely mounted on theworm-spindle, so that normally it will allow a free rotation of the wormand can be fed along the latter in either direction. To bring thehead-piece 10 into engagement with the worm, so that in rotatin thelatter the head-piece will be fed forward, to ether with the knife, abolt 32 is loosely gui ed through a bore 33, arranged transversely tothe worm in the head-piece 10, which bolt has at its inner endprojecting toward the spindle worm-thread 34, which is adapted to meshwith the worm-spindle when put in engagement therewith. by means of asector-shaped arm 35, pivoted to a projection 36 on the head-piece 10.The lower edge 37 of the sector-arm is cam-shaped and adapted to bear ona collar 38 of the bolt 32. Within a slot 39 in the sector-arm 35 theupper end of the bolt 32 is guided, so that by turning the arm in acertain direction the ca1nshaped edge of the lever will press the boltinward and bring its threaded inner end into engagement with the wormspindle. A spring 40, arranged between the collar of the bolt 32 and thehead-piece 10, tends to draw the bolt out of engagement with the worm 4.

In using my machine the head-piece 10, carrying the knife, is adjustedat the rear end of the worm-spindle 4, and by lifting the knife-hold er18 the knife is placed to bear on Thereupon the bolt 32 is pressed downby the sector-arm 35, whereby the head-piece 10 is brought in meshingconnection with the worm. By the rotation of the spindle 4 thehead-piece will be fed along the latter as the knife will peel thefruit, which is revolved by the fork-shaft 7 and against which it ispressed by the coil-spring 20. The skin will be peeled off in acontinuous strip, which will enter into the annular space between thepiece 29 and the cone 25 and pass out through the perforated back of thering 25.

It is understood that various changes may be made in the different partsof my machine by those skilled in the art without deviating from thespirit of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a fruit and vegetable peelin machine the combination with a framean a rotary fork-shaft therein for the fruit or vegetable, of aworm-spindle rotatively borne in the said. frame, means for rotation ofthe worm-spindle and the fork-shaft simultaneously, a carriage looselymounted on the worm-spindle, a tubular projection at one end of the saidcarriage, a knife-holder comprising an open casing loosely mounted onthe said tubular projection, an arm projecting from the circumference ofsaid casing, a spring arranged in said casing, a second casingrotatively and adjustably borne on the tubular projection alongside thecasing of the knife-holder, means in said second casing to engage andwind up the said spring, means for adjusting the said second casing,means for coupling A the carriage with the wormspindle to permit of itsbeing fed along the same, and a knife at the forward end of theknife-holder, substantially as set forth.

2. In a fruit and. vegetable peeling machine, the combination with aknife-holder, of a knife comprising a truncated conical ring sharpenedat its upwardly-projecting base, a truncated conical guide-piece looselyfitting in the base portion of the said conical ring, a threaded pinprojecting centrally from said guide-piece through the conical ring andadapted to be screwed to the knifeholder, said pin allowing theadjustment of the guide-piece to project more or less outward from theconical, ring, whereby the thickness of the peel to be cut off can bevaried, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM VOGEL.
